[v3,0/8] tools/vhost: Reset virtqueue on tests

Message

Eugenio Perez Martin April 18, 2020, 10:22 a.m. UTC

This series add tests used to validate the "vhost: Reset batched
descriptors on SET_VRING_BASE call" series, with a few minor updates of
them.

They are based on the tests sent back them, the ones that were not
included (reasons in that thread). This series changes:

* Delete need to export the ugly function in virtio_ring, now all the
code is added in tools/virtio (except the one line fix).
* Add forgotten uses of vhost_vq_set_backend. Fix bad usage order in
vhost_test_set_backend.
* Drop random reset, not really needed.
* Minor changes.

The first patch of this patchset ("vhost: Not cleaning batched descs in
VHOST_SET_VRING_BASE ioctl") should be squashed with ("vhost: batching
fetches") (currenlty, commit e7539c20a4a60b3a1bda3e7218c0d2a20669f357
in mst repository vhost branch).

Thanks!

Changes from v2:
* Squashed commits with fixes.
* Back to plain vring_*

Changes from v1:
* Different base, since branch was force-pushed.
* Using new vring_legacy_*, as base uses them now.

This serie is meant to be applied on top of
